    api-ref: Fix a description for 'guest_format'
    
    There is a wrong format 'ephemeral' in the description.
    So remove it and valid formats ('ext2', 'ext3', 'ext4' and 'xfs')
    are added.
    The parameter is optional, so fix it as well.

  -----------------------------------

  The doumentation for the Compute API method "POST /servers" has bad
  examples for the block_device_mapping_v2.guest_format field. In the
  description of this field it says ephemeral is a valid option, but
  using it results in an error that says ephemeral is not a valid
  format.

  Current: "Specifies the guest server disk file system format, such as ephemeral or swap."
  Change to something like: "Specifies the guest server disk file system format. A valid value is ext2, ext3, ext4, or xfs"

  I got those valid values from here: https://github.com/openstack/nova/blob/faacfeb07646115e7c8c91584d0e467a3e0064d7/nova/virt/libvirt/driver.py#L8102
  It may not be a complete list though, as I'm not sure where else the guest_format value is used. This file was just where the traceback I got when I used "ephemeral" led.
